# When is Pi Approximation Day Celebrated

## A slice of Mathematical Delight

Pi Approximation Day is practically the lesser-known cousin of the famous Pi Day. You know, that delightful holiday where we celebrate the mathematical wonder that is Pi—the ratio of a circle’s circumference to its diameter. But the question is, when is Pi Approximation Day celebrated?

Well, then let’s solve this mathematical mystery!

The Clever Date Choice: July 22nd

### Firstly, why do we celebrate Pi Approximation Day on July 22nd?

The reason will absolutely blow your mind. While Pi Day falls on March 14th (get it, 3.14?), Pi Approximation Day struts its stuff on 7/22.

Because 22/7 gives us an approximate value of 3.14. That’s clever, huh?

### The History: From Ancient Babylon to Modern NASA

If we look back into the history, the concept of Pi was developed by many mathematicians over time including Egyptians ,Babylonians and the Indian sage Aryabhatta. The result over time , came as approximating Pi to 3.125.

Then came the Egyptians, with their formula yielding a close 3.1605. But it didn’t stop there. After that ,the great Archimedes, while playing with polygons he set Pi to stop somewhere between 3.1408 and 3.1428. He is indeed one of the math wizards of all time!

As centuries rolled by, mathematicians worldwide joined the Pi party. From the introduction of the Greek letter π to Leonhard Euler’s popularity boost, Pi became the talk of the town( town of mathematicians). But gradually it’s usage became popular among the rest of the world.

Nowadays, we’ve mathematicians calculating trillions of digits of Pi, with NASA casually using around 15 to 40 digits for calculations. Who knew Pi could reach such astronomical heights?

### Fun Pi Facts: Because Who Doesn’t Love Pie?

Did you know the first 31 digits of Pi don’t include a zero? But we should definitely appreciate the brave soul who recited over 44,000 digits of Pi—that’s dedication! Also, let’s not forget the ancient Egyptians, who blessed humanity with the gift of pie back in 5th century B.C.

But remember, Pi Day isn’t complete without a slice of your favorite pie. Whether you’re team coconut cream or staunchly defending cherry pie’s honor, it’s all about celebrating this mathematical wonders.

### FAQs:

#### 1. Why is Pi Approximation Day celebrated on July 22nd?
